Black saves their rook and threatens White's queen.
White's main and only good move is /9. Qxh7/. Not only does White win a pawn, their queen is positioned to come back to d3 to defend White's queenside when needed. Eliminating Black's h-pawn also turns White's h-pawn into a passed pawn, providing an important advantage when entering an endgame.
